> So according to my Internet research: if your symmetric crypto is twice as secure (key size) as needs be, it is future proof.
New attacks are discovered from time to time. It is unlikely someone will try to bruteforce your encrypted data. Much more likely that some vulnerability will be discovered in AES or the way you generate keys for it.
